It is the process of building various types of buildings, or the process of turning the lines on the design drawings into physical objects at a designated location. It includes foundation construction, main structure construction, roof construction, decoration construction, etc. Before a building is built, its building materials need to be mixed before they can be used. A mixer is needed in the process of mixing raw materials.

[0003] The utility model patent with application number CN202420329007.7 discloses a mixer for construction engineering, belonging to the field of mixing device technology. One end of the mixing box is provided with a support leg and a discharge nozzle, and the other end of the mixing box is provided with a feeding port and a motor. The output end of the motor is provided with a rotating shaft. The spiral blades can flip the material upward when the rotating shaft rotates counterclockwise to increase the mixing efficiency, and can push the material downward when the rotating shaft rotates clockwise to increase the discharge speed of the material.

[0004] In actual mixing processes, the angle and density of the mixing blades are fixed, which means that when mixing materials of different particle sizes and densities, the mixing angle and the density of the mixing blades cannot be flexibly adjusted, resulting in low mixing efficiency.

[0005] Chinese patent CN202420329007.7 discloses "A mixer for construction engineering" (publication number CN221772145U). The device includes a mixing tank. One end of the mixing tank is provided with a support leg and a discharge nozzle. The other end of the mixing tank is provided with a feeding port and a motor.

A shaft seat is fixedly connected to the inner wall of the limiting groove. A connecting block is rotatably connected to one end of the shaft seat. A scraper is fixedly connected to one end of the connecting block. A scraper head is provided at one end of the scraper head, and scraper teeth are provided at one end of the scraper head. However, the device has some drawbacks: the angle and density of the stirring blades are fixed, which means that the stirring angle and the density of the stirring blades cannot be flexibly adjusted when stirring materials of different particle sizes and densities, resulting in low stirring efficiency. Utility Model Content

[0006] To address the problems of the prior art, this utility model provides a construction mixer that allows for flexible adjustment of the angle and installation density of the mixing blades. It can adjust the mixing density and angle of the mixing blades during mixing, preventing excessive mixing resistance from causing equipment damage and also preventing insufficient mixing resistance from reducing mixing efficiency, thereby achieving the best mixing effect.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a mixer for construction engineering, comprising a mixing drum, a mounting frame fixedly connected to the upper end of the mixing drum, a mixing motor fixedly connected to the mounting frame, and a mixing shaft drivenly connected to the mixing motor. A transverse shaft is detachably connected to the mixing shaft, and multiple sleeves are fitted on the transverse shaft. Mixing blades are fixedly connected to the sleeves, and positioning bolts pass through the sleeves. Threaded holes matching the positioning bolts are opened on the transverse shaft, and multiple threaded holes are arranged in a ring around the circumference of the transverse shaft. A gate assembly for assisting material unloading is provided at the lower end of the mixing drum.

[0008] The above structural design allows for flexible adjustment of the angle and installation density of the stirring blades. This enables the stirring density and angle of the stirring blades to be adjusted according to the different materials being stirred, thereby achieving the best stirring effect.

[0009] Preferably, multiple transverse shafts are provided, and the ends of the transverse shafts are provided with external threads. The stirring shaft has a threaded opening that matches the end of the transverse shaft.

[0010] With the above structural design, the transverse shaft is threaded onto the stirring shaft, making it easy to install and remove the transverse shaft from the stirring shaft.

[0011] Preferably, the height of the outer side of the inner wall at the bottom of the mixing tank is higher than the height of the center position.

[0012] The above structural design facilitates the collection of the mixed material at the center of the mixing tank, and then discharges it from the center of the mixing tank.

[0013] Preferably, the gate assembly includes a discharge port at the bottom of the mixing tank, a gate for blocking the discharge port, a positioning cover for limiting the movement range of the gate, a control handle fixedly connected to the gate, a rear baffle fixedly connected to the control handle, and a front baffle fixedly connected to the control handle. The positioning cover is fixedly connected to the bottom surface of the mixing tank, and the front baffle is located in front of the rear baffle, with the height of the front baffle being lower than the height of the rear baffle.

[0014] With the above structural design, during unloading, the worker tilts the left side of the handcart downwards, with the left end of the handcart touching the rear baffle. The worker then pushes the handcart from right to left, causing the gate to move from right to left and open, allowing the material to enter the handcart. Next, the worker flattens the handcart, at which point the front baffle engages with the left side of the handcart. After unloading is complete, the worker pulls the handcart to the right, moving the front baffle to the right, blocking the unloading port with the gate. Finally, the worker tilts the left side of the handcart downwards again, disengaging the front baffle from the handcart, and then pulls the handcart to the right to move it away, thus achieving an automatic opening and closing effect, making it convenient to use.

[0015] Preferably, the positioning cover is racetrack shaped, the outer edge of the gate is fixedly connected to a protrusion, and the positioning cover has a slot that matches the protrusion.

[0016] The above structural design restricts the direction of gate movement and prevents the gate from detaching from the positioning cover.

[0017] Preferably, the lower end of the stirring shaft extends into the interior of the discharge port, and the lower end of the stirring shaft is fixedly connected to the spiral blades.

[0018] The above structural design prevents material from accumulating inside the discharge port and affecting the mixing effect.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] This device allows for flexible adjustment of the angle and installation density of the mixing blades, enabling regulation of the mixing density and angle during mixing. This prevents excessive mixing resistance from causing equipment damage or insufficient mixing resistance from reducing mixing efficiency, thus achieving optimal mixing results. When using a handcart to load materials, workers can easily open and close the device's gate via the handcart. Attached Figure Description

[0024] Figure 4 This is a schematic diagram of the transverse shaft structure of this utility model. Detailed Implementation

[0025] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 This utility model provides a technical solution: a mixer for construction engineering, including a mixing tank 1, a mounting frame 3 fixedly connected to the upper end of the mixing tank 1, a mixing motor 4 fixedly connected to the mounting frame 3, and a mixing shaft 41 drivenly connected to the mixing motor 4. The mixing shaft 41 is rotatably connected to the mounting frame 3 and is rotatably connected to the mounting frame 3 through bearings. A transverse shaft 51 is detachably connected to the mixing shaft 41. Multiple sleeves 53 are sleeved on the transverse shaft 51, and mixing blades 5 are fixedly connected to the sleeves 53. 4. The middle part of the stirring blade 54 is fixedly connected to the sleeve 53. The sleeve 53 is fitted with a positioning bolt 55. The transverse shaft 51 has screw holes that match the positioning bolt 55. Multiple screw holes are arranged in a circle on the circumference of the transverse shaft 51. When fixing the sleeve 53, the operator installs the positioning bolt 55 into screw holes in different radial directions or the same radial direction, so that the tilt angles of adjacent stirring blades 54 are inconsistent or consistent. The lower end of the stirring tank 1 is provided with a gate assembly 6 that can assist in unloading.

[0026] The mixing tank 1 is fixedly connected to the support leg 2, and the support leg 2 is provided in four sets in a rectangular arrangement.

[0027] The diameter of the stirring blade 54 gradually decreases from the middle to both ends to reduce the resistance at the ends. Furthermore, the two ends of the stirring blade 54 are chamfered to reduce the resistance to the rotation of the stirring blade 54.

[0028] To facilitate tightening of the transverse shaft 51, a hexagonal nut-shaped tightening block is fixedly connected to the transverse shaft 51, making it easier for workers to tighten the transverse shaft 51 with a wrench when installing it.

[0029] like Figure 4 As shown, the installation density and tilt angle of the stirring blades 54 are adjustable. By adjusting the density, they can be used to stir and process different materials. The stirring blades 54 located at the inner end near the transverse shaft 51 and the stirring blades 54 located at the outer end near the transverse shaft 51 have opposite installation tilt directions. When the stirring shaft 41 rotates counterclockwise, it drives the transverse shaft 51 to rotate. The stirring blades 54 on the inner side push the material upward, and the stirring blades 54 on the outer side push the material downward, thereby forming a circulation inside the mixing tank 1. This allows the material to move and tumble longitudinally, thereby improving the mixing effect of the material.

[0030] like Figure 4As shown, multiple transverse shafts 51 are provided, and the ends of the transverse shafts 51 are provided with external threads. The stirring shaft 41 has a threaded opening that matches the end of the transverse shaft 51, which makes it easy for workers to install the transverse shafts 51 on the stirring shaft 41 and to remove the transverse shafts 51 from the stirring shaft 41.

[0031] The height of the outer side of the bottom inner wall of the mixing tank 1 is higher than the height of the center position.

[0032] like Figure 2 , Figure 3 As shown, the gate assembly includes a discharge port 64 at the bottom of the mixing tank 1, a gate 62 for blocking the discharge port 64, a positioning cover 61 for limiting the movement range of the gate 62, a control handle 63 fixedly connected to the gate 62, a rear baffle 9 fixedly connected to the control handle 63, and a front baffle 8 fixedly connected to the control handle 63. The positioning cover 61 is fixedly connected to the bottom surface of the mixing tank 1. The front baffle 8 is located in front of the rear baffle 9. The height of the front baffle 8 is lower than the height of the rear baffle 9. A groove is formed between the front baffle 8 and the rear baffle 9 to hold the handcart.

[0033] The positioning cover 61 is racetrack shaped, and the outer edge of the gate 62 is fixedly connected to the protrusion 66. The positioning cover 61 has a slot that matches the protrusion.

[0034] The lower end of the stirring shaft 41 extends into the discharge port 64, and the lower end of the stirring shaft 41 is fixedly connected to the spiral blade 7.

[0035] Working principle: During use, raw materials are added into the mixing tank 1, and the mixing motor 4 is started, driving the mixing shaft 41 to rotate counterclockwise. The mixing shaft 41 drives the horizontal shaft 51 to rotate counterclockwise, and the horizontal shaft 51 drives the mixing blades 54 to revolve. The inner mixing blades 54 revolve, stirring the material on the inner side while conveying it upwards. When the material reaches the top, it is turned outwards. During the revolve of the outer mixing blades 54, the material on the outer side is conveyed downwards, thus forming a circulation of material inside the mixing tank 1, preventing sedimentation at the bottom of the mixing tank 1. At the same time, the mixing shaft 41 drives the spiral blades 7 to rotate, stirring the material inside the discharge port 64. To prevent sedimentation inside the discharge port 64 from affecting the mixing effect, during unloading, the worker tilts the left side of the handcart downwards, with the left end of the handcart touching the rear baffle 9. The worker then pushes the handcart from right to left, causing the gate 62 to move from right to left and open. The material enters the handcart from the discharge port 64. Next, the worker flattens the handcart, at which point the front baffle 8 blocks the left side of the handcart. After unloading is completed, the worker pulls the handcart to the right, moving the handcart and the front baffle 8 to the right. The gate 62 moves to the right, blocking the discharge port 64. Finally, the worker tilts the left side of the handcart downwards again, disengaging the front baffle 8 from the handcart. Then, the worker pulls the handcart to the right to move it away, completing the unloading process.
